Abstract
Transient diffuse reflectance spectroscopic analysis using a femtosecond white-light continuum as a probe pulse was applied to commercially available catalysts of TiO2 powder; ”standard TiO2 catalysts” (JRC-TIO-2 and -4) supplied by the Catalysis Society of Japan. The ultrafast dynamics of photogenerated charge carriers under vacuum and air conditions was compared and discussed.Keywords
